The Gamma Doradids meteor shower takes place within the boundaries constellation of the Dorado. The meteor showers occurs between 27 Aug- 3 Sep with the peak occuring on the 28-Aug every year The Solar Longitude, mistakenly known as Lambda Omicron is 155.7 degrees. This value sometimes expressed as S.L. or λ ☉ is the the date of maximum activity. It is measured as a degree with zero degree indicating spring equinox (roughly March 21st/22nd). 90 is the Summer Solstice, 180 is the Autumn Equinox and 270 is the Winter Solstice. This degree is independent of the calender. AMS .
The closest star to the radiant point of the meteor shower is Gamma Doradus. The coordinates can also be determined by the Right Ascension (61.2) and the Declination (-50.2).
The Zenith Hourly Rate or how many you expect to see during the hour is 5. The ZHR can radically increase if the comet or associated object is close by. The speed/velocity of the Meteor Shower particles is 40 km/s.
